A group of researchers (two psychologists and a composer) with truly lovely research interests recently embarked on a mission to create music that was designed specifically for domestic cats’ enjoyment. In the study, published last month in the journal “Applied Animal Behaviour Science,” the researchers write of their hypothesis: “In order for music to be effective with other species,” they write, “it must be in the frequency range and with similar tempos to those used in natural communication by each species.”
